Well, we have legacy code where stdClass is quite prevalent and the code
works just fine!
In case of deprecation of stdClass I would like to point out that the
benefit of replacing "new stdClass" with "new DynamicObject" in our
existing code is absolutely zero. However, using DynamicObject in new
code has a benefit since the intent is clearer.
I think one also should take into account how much is stdClass described
in documentation and books. Reason is that deprecation is not just about
how it affects code. I'm a bit of a book worm so I'll check up on how
the usage of stdClass is described in some PHP books.
If deprecation of stdClass is on the table I think it should target the
last 8.x or 9.0 zero release.
